    My computer fan turns on from the moment the computer boots up to the moment I turn it off. It doesn't seem to matter whether it is hot or not.
    I've not installed any other hardware since I've had it so has anyone got any ideas?

    Hi!I'm not a expert in that matter but i think that it is normal that the fan(any fan)starts to turn once you switch on till you switch off the pc.About temperature,whether it's hot or not,this concerns the cpu fan which remains on but the speed it turns changes as the cpu temperature changes,in other words,it turns at variable speed.But other fans will turn at same speed unless you have a fan controller from which you can adjust the speed of the fan/s manually.But the fan/s remaining on till you switch your pc off is normal.

    But now there's something that i've noticed lately which is different from my pc and other people's pc i know.On my pc the cpu remains on even when my pc is on stand-by mode but the another day i've seen a pc(dell)and another one in another country(using an Athlon 3800+ X2 dual core)where the cpu fan actually turns off when the pc is put on stand-by mode and turns on once leave that mode.

    Some fans are usually on all the time, ie an exhaust fan (case fan) at the back. Most other fans are usually variable speed, ie only work when needed. My laptop has a fan underneath, and is on most of the time when the laptop is working hard, ie certainly when i'm running seti@home or encoding dvd's the CPU is maxxed out hence the CPU fan needs to be on to get rid of that extra heat.

    Thanks for the advice.
    The problem is simply the noise. What a racket!!!
    But if there's nothing I can do, I'll have to live with it I suppose.

    indeed; and on my burner PC i even put a variable speed fan in place of the case fan which made the PC real quiet, however the inside of the PC was getting much hotter (bad move) so i ditched that daft idea (was worth a try for a laugh though); in the end i bought a more efficient but much quieter (non-variable speed) case fan; job done
